Detecting cancer might be AI’s most altruistic and convoluted challenge yet. Standard screening methods such as radiological imaging can miss signs of cancer, or return a false negative (as it does in 20-30% of cases). The process of scanning images is particularly in need of improvement, as doctors must often visually search for signs of cancer which can leave only the largest, most advanced tumors to be detected. Hereditary testing is another detection method that determines genetic predisposition to cancer, but this does not provide much detail and cannot reveal if a person has cancer now.
